Pilot Ron Bramlage, his wife and four of their kids were all killed when their plane crashed near Lake Wales on June 7.

The family was returning to their Kansas home following a vacation in the Bahamas. They were flying in a plane Bramlage had purchased just weeks before.

Their planned trip was going to take them from Port St. Lucie to Junction City, Kan., but they never even made it out of Florida.

The preliminary NTSB report does not discuss the cause of the accident, but it details what happened in the moments leading up to it.

According to Air Traffic Control in Miami, at 12:32 p.m., Bramlage was flying at 24,000 feet when he was advised to avoid a large thunderstorm northwest of Lakeland.

At 12:33, the plane climbed to 25,000 feet and appeared to change direction, but the report indicates that in the next 30 seconds, the plane descended to 22,500 feet, and another 30 seconds after that it plummeted to 10,700 feet.

Approximately one minute later, the plane crashed near Lake Wales, according to the NTSB findings.

A pilot of a nearby plane reported hearing a mayday call in the minute before the crash.

WESH 2 helicopter pilot Dan McCarthy pored over the NTSB report and said it sounds like in the process of trying to change course and avoid the storm, Bramlage may have become disoriented due to the lack of visibility. It is also possible in trying to regain control, Bramlage stalled the plane.

"Unfortunately, this is an accident that I think, when it's all said and done, will fall back on the pilot," said McCarthy. "It's going to show that the pilot whether it's lack of experience or lack of knowledge of that particular aircraft. It looks like the aircraft was just purchased within the last 30 days of this crash and that he wasn't familiar with it."

In the report, witnesses said they saw the plane spiraling as it approached the ground and that parts of it already appeared to be missing.

McCarthy said it's possible pieces of the wing were sheared off as the plane plummeted to the ground.
